A sample of octane in equilibrium with its vapor in a closed 1.0 L container has a vapor pressure of 50 torr at 45oC. The container’s volume is increased to 2.0 L at constant temperature and equilibrium is re-established. What is the vapor pressure? The a...

A scraper is drawn over a tooth 22 times, each time moving a distance of 0.75 cm. The scraper is held against the tooth with a normal force of 5.4 N. Assuming a coefficient of kinetic friction of 0.90 between the scraper and the tooth, determine the work...

A footballl is thrown directly toward a receiver with initial speed of 18.0 m/s At an angle of 35.0 degrees above the horizontal. At that instant, The receiver is 18.0 m from the quarterback. In what direction and with what constant speed should the recei...

An 8.00g bullet is fired at 220m/s into a 250g wooden block that is initially at rest. The bullet remains in the block and after the collision the two slide up a 30° incline. a. Solve for the velocity of the bullet-block after the collision. (ans: 6.82m/s...

suppose you added 26.0 ml of 0.01 M NaOH to the solution, what is the molarity of excess NaOH in the mixture? what is the ph of this solution?

How many positive odd integers between 100 and 10000 can be formed using the digits 2,3,4,5 and 6

Hi, I am flunking really hard on this year ( this is my first year on it) and would it be so hard if you guys could maybe put the answers in here with the questions so maybe we could get some " extra help", anyway please and thank you.

It is the associative property Eliza!

I think you should ask your parents or older siblings or teacher!

Lilly and Abby r both right

FINALLY. this^^ is correct.

I know that the Louisiana Purchase doubled the united states in 1803... so, 2.) B.

First draw a picture. So draw a stick figure looking at a tree. So the figure (you) is 22 ft away from the tree, so draw a line from you to the tree and label it 22ft. Next you said that you look to the top of the tree which is 33 ft away, then draw a lin...

I am sorry I got ahead of myself! It would be kind of important! We have 26.0 ml 0.01 M NaOH and we are adding it to 25.0 ml 0.01 M HCL. what is the molarity of excess NaOH in the mixture?

0.0000196 = M?

oh okay! I see what I did wrong. I forgot the 0 out of the 0.051. I had 0.01/0.51 and that gave me too many zeros. So then how would you calculate the pH of the solution?

It's actually A.
